SAFETY JEWEL-BOX.

Patented Apr. 10, 1917.

Application filed April 16, 1915. Serial No. 21,853.

To all whom it may concern:

Be it known that I, Josnrn EDWARD BUR- nnnn, of the city of lVinnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Safety .leweLBoxes, of which the following is the specification. j

The invention relates to improvements in safety jewel boxes and the principal object of the invention is to provide, as a permanent fixture in a display table, a self closing jewel box wherein the jewel expert, showing the jewels to a possible customer,

can insert the usual jewel case and can, at-

will, quickly and easily openthe box to remove successive packages of jewels from the case for display purposes and after such removal, owing to the self closing feature of the box, can show the removed jewels'to advantage and with undivided attention. A further object of the invention is to construct a jewel box which, when closed, will safely house the jewels contained therein and thereby avoid any possibility of sneak thieving and further, one which, for opening or closing'purposes, does not require hand manipulation. A still further object of the invention is-to provide, in combination with the safety jewel box, an indicator which will show positively whether the jewel case is in the box ornot when the said box is closed. A still further object of the invention is to construct a jewel box embodying the above features so that it will have a neat and pleasing appearance when in stalled in a table and also one, the parts of which can be readily assembled, adjusted or repaired.

With the above objects in view the invention consists essentially in a top plate having an entrance opening therein, a box like casing carried by the plate and entered through the opening, a flexible, slidable, sectional shutter normally closing the entrance opening, spring means retaining the shutter normally closed, a shiftable carriage mounted on the casing, means for shifting the carriage, means actuated by the carriage in shifting for opening the shutter and an indicator associated with the plate and operated from the interior of the box, the parts being arranged and constructed as hereinafter more particularly described and later pointed out in the appended claims.

Figure 1 represents a plan view of the jewel box as it appears installed in the corner of a table top.

Fig. 2 represents a side view of-the corner of the table top showing the location of the box therein and the'location of the knee pedal.

Fig. 3 represents an enlarged vertical sectional view longitudinally through the box.

Fig. 11 represents a plan view of the indi cator and adjacent parts, the carrying pin being shown in horizontal section.

In the drawings like characters of refer- ?ince indicate corresponding parts in each gure.

In order that this invention might be better understood, I consider it advisable to first explain the present practice of showing jewels, particularly precious stones such as diamonds.

These are ordinarily contained in packages within a case, the various packages containing the various qualities and weights of stones. The case is usually taken by the diamond expert to a show room and placed on a table, and he according to practice, has to remove and replace the various packages when showingand to safe-guard himself usually keeps his left arm on the closed case and displays the open package as best he can with his attention divided. With my invention, oncev a package of jewels is taken from the case in the jewel box, the expert can show the jewels of that package to advantage as his attention is undivided and both his arms are free. Obviously, this is due to the self closing feature of the box as liereinbefore intimated.

Referring now to the drawings; v

1 represents a table and 2 my jewel box which is mounted, as a matter of convenience, in the left hand corner of the table. The table is cut away to admit the box and the top of the box is countersunk in the top of the table so that the upper face of the 9 and 10 and a bottom 11. These parts are all securely fastened together such as by brazing and are connected to the underside of the top plate in a similar manner. The interior of this casing is approached through the entrance opening.

The upper edges of the casing sides are offset as indicated at 7 longitudinally disposed and opposing channels 12. and 13 immediately beneath the inner edges of the top plate. These offset portions have their inner ends stopping short of theinner end of the box as indicated at 14 in order to escape the double pulleys as later described.

'15 is a flexible, sectional, slidable shutter normally closing the entrance opening. The sections of this shutter are all similar and 'they are constructed in detail as shown best extending end guides 19 and20.

On the underside they are provided with more or less T-shaped cross slots 21 and 22 which are designed to receive connecting flexible straps 23 and 2 1. Portions of the underlying flanges of the slots are removed as shownat 25 and 25 to allow of the partial escape of the straps and the slots.

Theunder corners of each strip at the side are beveled off as shown at 26 and 26.

The sections'are all designed so that the guides 19 and 20 thereof will fit slidably within the channels 12 and 13 with the shoulders 17 and 18 adjacent the side of the entrance opening in the plate. T 1e depth of the shouldersis such that wheir the sections are inserted, the upper faces of the sections are flush with the upper face of .the plate.

In assembling the shutter the various sections comprising it are placed side by Side and the flexible straps 23 and 24-, which are approximately the fulllength of the shutter,'ar'e passed through the T slots and have their ends fastened permanently to the two and 8 to provide end sections only. This method of constructing allows of quick assembly and also provides, when completed, a particularly strong yet flexible shutter.

It is here emphasized that the shutter, when closed, entirely fills the entrance opening and has the upper face flush with the face of the plate.

On the sides of the box and toward the inner end, I have mounted outstanding spindles 27 and 28 which carry each, rotatably, double pulleys 29 and 30, such pulleys being cast integral.

The pulleys 29 have their peripheries grooved to receive cables later referred to.

The rims of the pulleys 30 are partially cut away at the inner side of the peripheries to provide continuous seats 31 and 32 for the ends of the shutter sections when the said shutter is opened.

The pulleys 30 are arranged to house flat coiled springs 33 having their outer ends adjustably fastened at 33* in any suitable way to the sides of the box and their inner ends permanently fastened to the hubs of the pulleys.

The inner end section of the shutter is fastened permanently to the pulleys 30 by inserted angle brackets 34 and 35. These angle brackets are designed, in the normal or closed position of the shutter, to hold up in place the end section to which they are attached as well as form a connection between the shutter and the pulleys.

In this connection I might remark that in the turning of the pulleys in the direction indicated by the arrow a, Fig. 3, the successive sections of the shutter are drawn out of the channels 12 and 13 and onto the pulleys 30, the ends of the sections riding in the seats 31 and 32. In the continued opening of the shutter, the sections are wound around the pulleys 30, so to speak, the final open position of the shutter being limited by the engagement of the brackets 34 and 35 with the underside of the box.

It is necessary to bevel ofi' slightly the inner end of the entrance opening as shown at 36, to allow for clearance in the opening of the shutter, (see Fig. 3.)

Cables 37 and 33 are passed around the flanges of the pulleys 30 and are fastened to the same at 39. These cables extend from the pulleys to the front of the box and after being passed around guide rollers 40 and 40*, located at the front end of the box, enter the forward ends of the channels 12 and 13 and are fastened to the forward end of the shutter. Accordingly, owing to the action of the springs 33, the cables tend to resist any opening action of the shutter or conversely upon the shutter being opened, the cables operate under the action of the springs to automatically close the shutter.

On the forward end 10 of the box I have mounted a carriage 41 which is arranged to be shifted laterally by the action of knee pressure on a pedal 42 attached thereto. The detailsof these parts are now described;

43 and 44 are parallel, horizontally disposed tracks, permanently secured to the end of the box and between which I have mounted pivoted rollers 45 and 46, such rollers being carried by connected pins extending between side bars47 and 48.

49 is a vertically disposed arm having the upper end permanently secured to the outer side bar 47 and the loWer end pivotally connected by means of a pin 50 with a swinging arm 51 which is to be engaged by the knee 51.

The swinging arm carries an ofiset 52 which engages, in a location above the joint,

with the stationary arm 49 in a manner such that the joint is kept against breaking when the lower end of the arm 51 is pressed in a left hand direction. In other words, the arrangement is such that when the lower end of the pedal is pressed to the left by the knee, the carriage is forced to move to the left on the tracks.

A coiled spring 53 is provided at the joint between the arms, such spring having a natural tendency to swing the lower arm in a right hand direction to fold the same up when not in use. In the drawings I have shown this lower arm in an unnatural position, that is to say, the said arm would not retain the position shown unless held against the action of the spring 53 by the pressure of the knee in a left hand direction.

A cable 54 is passed around and connected to one of the pulleys 29 and extends over suitable guide rollers 55 and 56 secured to the side 8 and end 10 of the box and has the extending end thereof passed around a suitably located guide pin 57 and finally fastened to the outer plate 47 of the carriage.

A second cable 59 is passed around and fastened to the other of the pulleys 29 and after passing over a guide pulley 60 secured to the side 7 of the box, is finally fastened also to the end of the outer plate 47 of the carriage. This arrangement of cables is such that when the carriage is moved.

laterally to the left by the pressure on the pedal, the cables 54 and 59 eifect the turning of the pulleys 29 on the spindles and the consequent rotation of the pulleys 80. The result is, as will readily be observed, that by pressing the knee pedal, one opens the shutter against the action of the springs 83, and that immediately the knee pedal is re leased, the shutter will automatically close.

In order that the shutter can be locked closed, I have provided a lock 61, at the forward end of the box, this lock being manipulated by a key and being designed to lock the shutter to the end of the box. I

have not enlarged .on the construction of this lock as it actually forms no part of this invention.

In order to avoid the possibility of the usual jewel case being carelessly left in the box, I have provided an indicator, operated from the interior of the boX, by the weight of the jewel case, and in such a manner that if the jewel case be in the box, the indicator will show a signal. This device is now described;

62 is a short spindle slidably mounted in the bottom of the box and having the upper end enlarged into a head 63 contained within the box and the lower end forked beneath the bottom of the box and carrying a roller 64.

65 is a further roller mounted on the bottom of the box at one side of the spindle and 66 is an eye located at the opposite side of the spindle.

67 is an indicator in the form of a segment pivotally mounted on a pin 68 extending downwardly from the underside of the plate 4. This indicator is held normally pressed against a stop 69 by a spring 70 mounted on the pin and it has the upper face thereof marked to present differently colored 'circular spots 71 and 72, these spots being arranged, in the swinging of the segment, to sweep beneath the sight opening 73 located in the plate 4. By preference, I desire the spot 71 to be red in color while the spot 72 is to be the same color as the finished color of the plate surface.

A cable 74 or other flexible connection is fastened to the segment and passes first over rollers 75 and 76 secured to the side of the box and then over and around the rollers 64 and 65 and is finally fastened to the eye 66. This cable is normally held taut by the action of the spring 70 and when so held, it will be seen that the head 68 will be forced up into the box. With the head in this position, it is obvious that the spot 72 is appearing through the sight opening.

Supposing one has left the jewel case in the box, this is quickly detected the instant one looks at the plate for the reason that the red spot will be showing through the opening. The red spot is showing through the opening for the reason that when the jewel case was placed in the box, the head Was forced down by the weight of the case and consequently pulled the cable in a direction such that the segment was swung over to expose the red spot 71 in the place of that 72.

Although I have shown and described the various parts of this appliance in detail, still I wish it to be distinctly understood that these may be changed or modified, under the scope of the appended claims, without affecting, in any way, the spirit of the invention.

What I claim as my invention is 1. A safety jewel box comprising, a box like casing having an entrance opening in the top thereof, a flexible, sectional, slidable shutter closingthe entrance opening, a pair of cables connected'to the forward end of the shutter, a pair of rotatably mounted pulleys located beneath the rear end of the shutter and to which the cables are fastened, guide pulleys for the cables, springs attached to the first mentioned pulleys and effecting a pull in the cables to retain the shutter normally closed, means permanently connecting the first mentioned pulleys with the rear end of the shutter and pressure operated means for rotating the pulleys against the action of the springs and effecting the opening of the shutter and the winding of the same on the pulleys.

2. A safety jewel box comprising, a box like casing having'an entrance opening in the top thereof, a flexible, sectional, slidable shutter closing the entrance opening, a pair of cables connected to the forward end of the shutter, a pair of rotatably mounted pulleys carried by. the casing and located beneath the rear end of the shutter and to manently connecting the rear end of the shutter to the periphery of the pulleys, a shiftable carriage mounted on the forward end of the box, a pressure lever for shifting the carriage, a second pair of pulleys connected to the former pulleys, cables connecting the latter pulleys with the carriage and suitably located guide rollers carrying the latter cables and arranged to effect, in the shifting of the carriage, the pulling of the latter cables to rotate the pulleys and open the shutter against the action of the springs and wind the shutter on the former pulleys. Signed at Winnipeg this 17th day of March 1915.
